Differences in weight are much more sex related (male 476 g female 610 g), than 
age related. It isn't that easy to distinguish age categories in this species. 
They do hover but not very well.

At 11:00 a.m. today, in the Pegasus Riding School car park, Holt I 
watched as two Black-faced Cuckoo-shrikes hurtled by and entered a 
nearby tree. A moment later a Brown Falcon arrived about three metres 
directly above the tree and hovered, as  the books tell us, "clumsily," 
for a second before flying away. I've read or heard somewhere that if a 
Brown Falcon hovers it's probably a younger, lighter bird because the 
higher wing loading on older and likely heavier birds would prevent 
hovering. 😕 Any comment?
